IMPROVED BRICK-MACHINE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I,`PHILIP H. KELLS, of Adrian, Lenawee county, State of Michigan, have invented a certain new and useful Improved BrickdVIachinc; and I do hereby declare the following to be 'a full, clear, and exact description of the same, reference being had to the accompanying drawing, -which forms part of this specification.

My invention relates to that class of brick-machines in which the mould-wheel revolves in ahorizontal plane, and consists in improvements in the devices employed for supporting the bed-plate of the pug-mills, and

the followers of themoulds; and for filling the moulds, and pressing and smoothing the brick.

Figure 1 represents a central vertical section of my improved machine, through. the line 'x x, ,'tig. 2. Figure 2 represents a plan view with the pug-mill and gearing removed. Figure 8 represents a side `elevation of the lower` portion of the machine, cut off at the line xx, Iig'. 1; and Figure frepresents a vertical section in the plane indicated by the line y g/,fig. 2. In the drawings-4 .A represents the base or foundation, which may be of iron or other proper material.

A A represent supporting-dolumns, upon which the bed-plate rests, which columns are provided at their lower ends with screw-threads. as shown, which {it into corresponding threads in the sockets a a. The upper ends of these columns are also received into proper sockets in the lower side of the bed-plate, being so arranged as to revolve freely therein.

a represents a socket, which is intended for the reception of the end of a lever, hy which means adjustf ment of the columns is made np or down, as desired.

B represents the bed-plate, which rrests securely upon the columns A A', Iand is provided with 'the ring B', upon which latter the pug-mill rests, as shown in fig. 2.

b b, figs. 2 and 4, represent two openings in the bed-plate, within the pug-mill, which openings are sepa.- rated by the centre-piece b. This centre-piece is made wedge-shape in form, as shown in fig. 4, and is so arranged as to present its inclined f ace to the mould-wheel as it revolves toward it.

CIepresents the pug-mill, which is constructed and arranged in the usual manner.

D D represent standards, rising from the' bed-plate B, which support thejupper 'platform and gearing.

E represents the upper platform, through which passes the shaft El of the pug-mill, upon which latter are placed the grinding-knives, which disintegrate and force down the clay.

Upon the upper end of the-shaft El is placed the bevel-gear wheel E2, which engages with the pinionfof shaft F, which latter is supported in suitable bearings rising from the standards 4D D, as shown in figs. 1 and 4.,

F represents a gear-wheel upon shaft F, which engages with the pinion g'upon shaft G. By means of the shaft G, power is applied to the machine.

II' represents 'avertical shaft, resting in suitable bearings in the bedplate B and upper platformE, upon the upper end of which is located thc bevel-gear wheel h, engaging with pinionf upon shaft F. Its lower end is provided with the pinion t, below the bed-plate, which; engages with the intermediate gear-wheel hz, by means of which latter the mould-wheel is operated..

I represents the mould-wheel. The lower and inner edge rests upon the ring I', and ,revolves freely thereon, being operated by means of the teeth upon its outer edge. l v

The mould-wheel is kept securely in place hywmeans of the projecting flange/z' upon the ring I, the wheel being provided also -.\vith a shoulder, which projects o ver and rests upon this lange, .as clearly shown in Iig. 1'.

il il, iig. 2, represent the moulds, which are arranged in the wheel ir'the usual manner. '3 il represent thel followers, which in this case consist ofa block corresponding in size with the mould, which block is provided with the arms zil i3, between which the friction-wheel is placed, as shown in iig. 1.

K K represent annular rings, of wrought iron or analogous material, which are bolted securely to the mould-wheel, vupon its under side, the opening between'whieh is just sutlici'entto allow the arms 32 of the fol-` lowers to pass through.

L represents a ring, of varying height, located directly beneath the friction-wheels of the followers, as shown in fig. 4. I

M represents a smoothing-plate, securely attached to the under side of the bed-plate B, directly over the moulds, whichis provided with a cutting-edge, as shown in iig. 4.

N, iig. 2, represents a supplementary knife, located in rear of smoothing-plate M, which cuts o any surplus clay which may accidentally adhere after passing the smoothing-plate.

O represents an additional plate, placed in rear ofknifc N, which gives the surface of the brick ainal touch.

From this description, the nature and operation of my invention will readily be understood.

The clay having been put vinto the pug-mill, the machine is set in motion.

It will be observed that by the peculiar arrangement of gearing described and shown, the shaft of the pugmill and the mould-wheel are made to turn in the same direction, the revolution of the shaft, however, being much more rapid than that of the mould-wheel.

The openings through the bed-plate permit the clay to pass intoA the moulds, the latter being perfectly filled by the action of the blades e, iig. 4, and centre-piece b', for the latter, being wedge-shape, permits an unusual amount of clay to enter between itself andthe mould, which surplus is necessarily forced into the mould as the wheel revolves.

The operation thus described could not be thus performed unless the revolution of the shaft and mouldwheelwere in the same direction. v

The moulds having been filled, pass the cutting-edge of the smoothing-plate M, by which means the surface is rendered level, then under the knife N, and also the plate O, by which latter the iinaltoueh is given.

It will be observed that the ring L, by which-the followers are operated, increases slightly in height at l, directly beneath the smoothing-plate M, by which means additional pressure is given the, clay at this point, as is clearly shown in iig. 4.

The bricks'are discharged nal-ly from thefmoulds by the action of the followers, which latter are forced up by the cam'or incline l on the ring L, as is clearly shown in figs. 1 and 3.

The bed-plate and pug-mill may be adjusted into the precise position desired, relative to the mould-wheel, by means of the adjustable column A' A.

Having thus fully described my invention, what I claim 'as new, anddesire to secure by Lettere Patent, is-

1. The annular wrought-iron rings K K', in combination with the mould-wheel I and followers i?, substantially as and for the purpose described.

2. The provision, in the bed-plate B, of the openings b b, and wedge-shaped centre-piece b,substantially as and for the purpose specified.

3. The adjustable'columns A A', constructed and arranged as described, in combination with the bedplate B and pug-mill C, substantially as and for the purpose set forth.
